Stop the Drip, Hold the Heat
Pole barn and shop insulation solves two problems in north-central Ohio. In winter, a bare steel building loses heat as fast as you can make it. In spring and fall, warm, damp air inside the building hits cold steel panels and condenses, so water drips from the roof onto equipment, hay, vehicles and tools. Closed-cell spray foam applied directly to the steel stops both: it insulates, and because it bonds to the metal there is no cold surface left for moisture to form on.
Why foam instead of batts
Fiberglass in a post-frame building tends to sag, collect moisture behind it and give mice a home. Closed-cell foam is rigid, sticks to the panel, and adds about R-5 to R-7 per inch according to HomeGuide. It also seals the seams and fastener holes that let wind through the walls.
Who calls us
Farmers around Lucas, Butler, Bellville and the townships outside Mansfield with machinery sheds and livestock barns. Hobbyists and contractors with heated shops. Homeowners with a detached garage they want to turn into a workspace. Each building is different: some need foam on the roof only to stop dripping, others need full walls and roof to hold heat.
Planning the job
We look at the building's use, heat source, doors and ventilation. A heated shop needs a different thickness than a cold storage barn. Foam left exposed in a building used by people may need a coating or barrier, depending on the product listing and how the building is used; we tell you which applies before we price.

Pole Barn & Shop Insulation Questions
How thick should foam be in a pole barn?
It depends on use. A cold storage barn may need only enough to stop condensation; a heated shop needs more. We size it to how you use the building.
Can you spray foam in winter?
Yes, with care. The steel and the foam both need to be within a working temperature range, so we may need heat in the building first.
Will foam stop my barn roof from dripping?
Yes. Dripping comes from moist air hitting cold steel. Foam bonded to the steel removes that cold surface.
Do farm buildings need a permit?
Rules for agricultural buildings differ from houses. Check with the Richland County building department for your project.
